my iphone is less than a year old, at least in use that long...it was a bulk purchase years ago and sold individually a year ago, so not turned on or actived till last year...
After upgrading to ios 14.1 it drains 1% every 30 seconds.
it discharges while plugged in on any cable i've tried...
I get 50 min at best
Apple says to restore but i know like every other time i'll lose lots of data and apps.
